Be it known that I, SAMUELB. CLAYTON,

a citizen of the United States, and a resident of Greensboro, in the county of Guilford, and State of North Carolina, have invented certain-new and useful Improvements in -Automobile Locks, of which the following is a specification.

This invention relates to an improvement in automobile locks of the type forming the subjectmatter of my prior Patent Number 1,395,906. I

The object of the-invention is to provide a locking device of this character which is adapted for use with various types of steering mechanism and in which the lock mech anism is embodied in the lock itself and is housed and protected without in any way.

impairing the universal capabilities of the lock, the device being at the same time of.

ing had to the accompanying drawings forming part of this specification, and in which:

Figure l is a perspective view, showing the preferred embodiment of the invention;

Figure2 is a View, partly in longitudinal central section and partly in elevation, the parts being shown in different positions in dotted lines; and v r Figure 3 is a view in transverse section through the body portion, parts being shown in elevation for the sake of illustration.

Referring to the drawings, the numeral 10 designates the body portion of the frame of the lock whichis provided with marginalfianges 12, the purpose of which willhere inafter more fully appear. At one end the bodyportion 10 is'provided with a locking slot 13 which extends entirely through the body portion. i

A yoke designated generally at 15, is pro vided and includes an arm 16 offset, as at 17, from thebody of the yoke andpivotally and reversibly mounted on the side flanges 1210f the body portion 10,this;mounting A of' theyoke being eflectedby pivotallycon necting the arin'16 to a block 18 as indicated at 19;and by pivotally mounting the block 18 on theside, flanges, as indicated at 20, the', block 20 being rotatable-in a plane at right angles ,tothe plane of rotation of'the arm 16 and the aXis of. rotationof thefarm and block. being spaced from each other, as;

clearly shown'in- Figure 2. The yoke 15 also includes alocking arm 2l-, the outerend portion of which is adapted to be received in the lockingslot 13. This arm 21 is-in the fo'rm. of a straight flat bar and may be entered or introduced into the slot 13 from 3 either side or end thereof, asindicated by full and dotted lines in Figure 2. The portion of the locking arm 21 which isdisposed within the slot 13 is provided with a trans verse opening, designated at 22, an dconsti tuting a bolt seat or socket in either position] of the yoke. j

The locking mechanism is embodied in the body portion 10 and accordingly the body portion 10 is provided with a longitudinally 1 1 extending bore 23 in which ,a 1061524915 mounted for slidingmovement. -The bolt24 18 adapted to be. projected across the slot 13 and into the seat 22 of the locking arm when the locking arm-is received in the slot 1-3 or the bolt 24 may be retracted entirely within v its bore 23. A compresslon coil spring 25 is arranged in one end of. the bore and one f end. of this coil spring engages'the adjacent end of the bOlt 241, the other end of thecoil spring abutting a plug 26 threadedinto the bore23. The compression coil spring 25 is of course under compression and tends to pro ect the bolt, asshown 1n Figures 2 and 8. A key controlledor permutation. lock 27 is provided for controlling the,bolt-21 ,this

lock-27 being fitted into a cavity 28 1112),-

chined or otherwise formed in the body portion 10 and communicating with the bore 23.

The lock-27 be of any known type or design: and preferably, includesa rotatable barrel 29 which carries a crank pin 30 operatively engaged with a notch 31 formed inthebolt 2 130 that as the key is turned;

in the look a crank pin will be turned and will impart a sliding movement to the bolt 24. I

A swinging arm is pivotally mounted upon a pin 36 extending transversely between; the side flanges 12 and the outer end of the swinging arm 25 is beveled as at 37 and is engaged with the ofiset portion 17 of the yoke, as shown in Figure 2. This arm 35 serves to restrict the internal areaof the:

yoke when such restriction is desired. A removable pin 38 extends transversely be tween the flanges 12 of the body portion and has screw threaded connection with one or more of these flanges so that it is 'releasably held in position. This pin 38' is located so that it engages the swinging arm 35 and holds the same in desired position.

l/Vith the parts arranged as shown in Figure 1, the lock is adapted for use with a I J -Coxtype of steering gear in accordance gear used on Dodge automobiles the pin with the showing of my prior patent, the internal end of the yoke being restricted for this purpose by means of the arm 35 in the present instance. If it is desired to adapt the lock for use with the type of steering 2. By shifting the pin 35 however the internal area of the yoke has been enlargedsufliciently to enable the yoke to encompass the drag link and the spindle and third arm of the steering gear of a Dodge automo bile.) If itis desired to use the lock uponthe type of steering gear used on a Ford automobile, the swinging arm 35 is disposed in the dotted line position but the yoke 13 is reversed with respect to the body, as shown in dotted lines in Flgur e 2 so that the locking arm 21 enters the slot 13 from the opposite side. With the parts so arranged the front axle and adjacent'parts of the steering mechanism are embraced by the yoke and held from operation. I

In all of the uses of the invention the lock "may be applied to the steering mechanism or taken therefrom by an authorized person without undue efiort or inconvenlence. In applying the lock it is only necessary to properly embrace the parts with the yoke and snap the. arm 21 into engagement with the bolt, the end of the locking arm being beveled, as at 21*, to facilitate this auto matic locking. It is to be understood ot ,course that the bolt 24 may also be double beveled at one .end to further facilitatethe locking action, if desired. To release the lock it is only necessary to insert a key in the slot of the barrel and turn the same through a revolution or a part of a revolu- 3 tion, as such turning of the key will retract the bolt and permit withdrawal of the looking arm from the bolt. Moreover the device may be readily adapted foruse with either the types of steering mechanism as has been previously described.

Although I have herein shown and described only oneform' of lock embodying my invention it is to be understood that various changes in the form, proportion and minor details of construction;;may be resorted to without departing fromthe spirit of the invention and the spirit and scope ofthe appended claims.-

I claim: 1. An automobile lock of the character.

2. An automobile lock of the character described comprising a body portion having a locking slot open in either side thereof, a yoke reversibly and pivotally mounted on said body portion and having a locking arm adapted to be entered into said locking slot from each side thereof, and locking means, carried by the body portion and including-a bolt engageable with a portion of the look ing arm received in said locking slot. 7 3. An automobile look of the character described comprising a body portion having spaced side flanges, a yoke associated with the body portion, a swinging arm mounted. on the side plates and having its ends adapted to engage a portion of the yoke for re stricting the internal area=- thereof, said swinging arm being adapted to be moved to;

described, comprising abody portion having mechanism carried by the body portion a locking slot, a yoke pivotally and re-.con1-prising a spring projected sliding bolt versibly connected to the body portion and having locking arm adapted to be rearm and key controlled means for retracting 5 ceived in said locking slot, the portion of the said bolt.
